I'm still working on the St. Paul campus AP.  I'm waiting to hear back
from the Facilities people over there.. They are going to install our
antenna mast.  Hopefully sometime soon.

802.11b chips are designed to handle diversity antennas.. aka, more than
one antenna.  Designing an anteanna to recive a variety of polarization
should help.  but this also has the disadvantage that you are listening to
more background noise.  the reason a lot of outdoor wireless stuff is very
polarized, is to help reject background noise, and reduce the noise floor.

these antennas would be interesting to try in comparison to standard
